AUTOMATIC ENVELOP AND CARD FEEDING ATTACHMENT FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented Feb. 28, 1911 Application filed February 10, 1909. Serial No. 477,162.

' the county of Camden and State of New Jersey, have invented new and useful [inprovements in Automatic Envelop and Card Feeding Attachments for 'lyperiters, of which the following is a specification.

our invention relates to improvements in automatic envelop, post card or index card feeding attachment for typewriters for feeding the same to the platen of a typewriter. The object of our invention is to provide an attachment which can be readily attached to the ordinary typewriter and in which a series of envelops, post or index cards can be. placed one against the other and fed separately to the typewriter i'iiaehine. as the completed envelop, post or index card is removed from the typewriter in the ordinary manner, all of which is operated by the platen of the t. v pcwriter.

Another object of our invention is to provide an attachment of this character having certain details of structure, whereby the envelops. post or index cards are fed to the platen of the typewriter in perfect alineinent and it, is not necessary to adjust the same after they enter the machine.

Another object of our invention is to provide an attachment of this character, whereby envelops of different widths may be accurately fed to the typewriter.

Referring now to the drawings, 1 reprecarrying the usual platen 2 rotated in the ordinary manner.

3 represents a frame having an inclined rear portion l and a horizontal front portion The horizontal portion at its forward end is provided with tongues t) and T, which are adapted to rest on the steps carried by the carriage of the typewriter. Said steps are those which are provided in some designs of typewriters to supportthe paper supporting plate at the rear of the platen. While we have shown this arrangement for attaching our device to the car-. riage of the typewriter, it-Will be understood that in some cases it is securedupon the carriage by any other fastening means adapted to the different makes and designs. The forward end of the inclined portion adjacent to the horizontal portion 5, is provided with upwardly extending ears 8 and 9, carrying the bearings and 11, in which is rotatably mounted the shaft 12. Said shaft, at each end, on the inside of the bearings, is provided with collars 13, keyed upon the shaft, whereby the shaft is held againstlongitudina-l. movement. The outer end of the. shaft has keyed thereon a gear wheel 14. The ear 8, in front of the shaft 12, has a ;hort shaft 15 secured thereto. This shaft constructed with an outer head portion 16 and an inner reduced threaded portion 17 upon which anut 18 is screwed for lock-.

ing' the shaft to the ear. The said shaft 15, on the outside of the car, has loosely mounted thereon a gear wheel 19 meshing w ith the gear 1%. Secured to the outer face of the gear 19 is-a sprocket wheel iZO'around which a link belt 21 passes. The platen 2 of the typewriter, at the right. has an o 'icratiug knob.21. This operating knob is l(ll\()\':il)l held to the platen by means of the screw 1'3. The said knob carries on its hub a sprocket wheel 23 which is in alineinent with the sprocket wheel over which the link belt. 21 passes for rotating the shaft 12. The shaft 12 atthe center provided with a i op forwardly extending: Ushap d franu- 2'1 ha\'- ing enlarged hearing PUl'UOllS 3.7 lou.-; rl'

' mounted upon the shaft. wl'icrehy the frame the fran'ie 24, is provided with a pcriplu-ral lroore in which the hifurcatt-d cnd of the member 29 rests. This arrangement, as will-he seen, prevents the outward movement,

of the shaft and yet allows the ready rc- Y moral of the shaft for the purpose hereinafter set forth. The plate is provided with a slot 30 t'l'irough which a stud 31, carried by frame 24.. passes, to prerent the plate from twisting out of, line on the fran'ie.

20 Passing tl'irongl'i the slot 30 i.-;-a set screw 32 which is screwed in the fame for holding the plate in its adjusted position. The innet-end of the plate is 'norided with an out- Wardlj turned cod 5:) to form a finger hold wherel'rv the plate is moved in or out.

Motn'itedon the shaft 26. within the frame is a spool-like wheel 34. which is adaptedto freely rotate upon the shaft. The onter el'ilarged ends of the spool meinher 3-1- form two feed rollers 35 and 36. which are adapted to engage the "envch'ips and. feed thein forward toward the platen. For the purpose of preventing the roller slipping on the envelo 'm, we secure upon the outer pe- 35 riphery thereof a tire or covering 3'7,'profirahly of ruhher transversely eorrtuz'altal. The spool 34 is provided with a gear 38 meshing: with the gear jifll'lfljltlhV keyed upon no shaft lz, wherchy the spool is rotated in 40 the direction of the arrow' in z and 3.

lt will he apparent that the frame fi l l'ieina placed forward of the shaft 12. the whet-l l l is adapted to shore the onrt-lops awa from itself and feed them l'rn'ward and toward the platen of the typewriter and into contact with the auxiliary l'eedin; nu-eha nisnr hereinafter described.

For the purpose of adapting our invention to the use of envelops. pod cards or index cards of rarying widths and dinu-n sions and insure their regular and.nnil'oi'in feeding into the proper position upon thc platen of the ty' aen'rittzr. it has Ira-n found neeessary to provide an additi nal fet d roller to ronvey the same to the platen. This feed roller i placed at the forward end oftheswingzirug frame A. whit-h \\'t' will now proceed to desrrihc.

The frame Q-l is prcl'i-rahlv made in two sections 40 and 41 leaving; :rspace 42 he tween the forward ends thereof. This spa is bridged by a stud or shaft' ll which rigidly connects the two sections of the frame and also serves as pivot for the auxiliary '3 frame carrying thTi additional feed froller.

Loosely mounted upon the :-tud or -hal'l l l: a swinging l'ranie -l-l mounted in a siinilar manner to the frame 21. The outer cud of aid stringing frame i.-; provided with a shaft l? whi h extends through the frame and carries at. the outside of the frame a pair of roller: i and 47 l'iaving' ruhher or other riction tires upon their pcri 'iht-ry which are adapted to feed the envelop forward to th platen. A

'llushaft l3 is-provided with an l lltgear niounti-d thereon adapted to driv a gear 49. \\'lllt'll in turn drives a our 30 which tll'i\ l the gearfil mounted on thc shaft 4-). and whcrel'i-y-the rollers 46 and 47 are rotated in the same direction as the roller: 3 and 35. As enrelops and index cards vary in width. as heretofore stated. the feed \l'lHt-l H6 and 37 cannot he set in a fixed disconnnodate cards of all widths, and it therefore hccon'ies necessary to adjust their po-.i-

tion to aceonnnmlate the larger sizes. 'l'hus ii has lit-en found necessary to provide the auxiliary feed rollers 46 and 47 to court the narrow r-ards or enrelops to thetype writer platen. Also it is liecessary to place the main swinging fame and feed rollers a suliieient distance hark to provide sutlieicnt space. to taluthe eards and env'elops front the typewriter without: buckling them.

One end of the farm: 3 being supported hy the carriage of the tyrwwriter it he-. conu-s ilt ..-ltl' to provide an additional su 'i iort at. the other and of the fame that will not interfere with the escapen'ient of thr- \"])e\\riter. This has het-n ar-con'ipliehrd hr prorit ling the rear end of the frame with a ring 5: to which is atta hed a hain or cord 5 the upper end of which may h attached to the ceiling or other supp rt ahore the typewriter. By this arrano'rinent it will he apparent that the weight of tho rt-ar nd of the frame i--: support d hy th hain. whi h nt-cesearily lainn approxiiuatelr Ht'f-It'l'l feet long will do scrih a very slight are, and will therefore. pot n'iat t-riallv rai-e or lower theearriag'c. This means of support has hccu found to ause the lead r':-i-lan e to the trart-l of the arriage upon the l \'p '\\riler.

'l'he l'ranufl is pro .id l at the Fl t with lonti'i-tudiuallr extending u'uid plates Bi and 3-1 whi h ar adapted to, form guides for the ends of the tllWlOll or card: to inaurithil -dint! of same in proper allurni nl lo the t rpt'wrilcr.

".lhe inner end: ol' th'e guide plates 54 and 5 3 are proridrd with upwardly curved arms 5! and till which areadapled to sapport and l 'l l llU liltl -riage consists of a rectangular frame 6 angle and push them forward.

rollers 36 and37 were allowed to rest on the prevent the envelops from falling upon the feed rollers as they are delivered from the platen of the typewriter.

To cause the proper feeding of the envelops to the feed rollers, ,it has been found advantageous to support them in an "inclined position at an angle of from thirty to fifty degrees according to the thickness of the cuvelop orcard. The frame 3, at the center, is

rovided with a slot 61 and carried by the ower face of the frame and below the slot is a rack bar 62. The envelop supporting carhavingat each side the rollers 64 and adapted to roll upon the upper face of the frame 3. Pivotally mounted at 66 to the forward. end of the frame is an inclined envelop supporting plate 67. In order to support the envelops or cards at the different angles, as heretofore set forth, the rear face of the plate 67 is provided with a segmental bar 68 which passes downwardly through a housing 69 carried by the frame 63. Extending through the housing 69 is a thumb screw 70 which engages the segmental bar 68 and locks it in its adjusted position. The said set screw 70 is in an elongated form and extends out flush with the plate 67. The forward end of the carriage is provided with a wheel 71 which extends through the slot 61 in the frame 23 and serves as a guide to'keep the carriage 63 at right angles to the frame 3. The rear endof the carriage 63 is provided with a transverse shaft 72 upon which is rigidly mounted a gear wlieel-75 extending through the slot 61 and engaging the rack 62. Surrounding the shaft 72 and secured thereto is a coil spring 76 which has one end rigidly secured to the frame 3. Said carriage 63, as will be seen, is adapted to. roll down the inclined portion of the frame by gravity, aided by the spring 76, and feeds the envelops to the feed rollers.

In replenishing a supply of cards or en velops in our devicc, the frame 63 may-be rolled up the incline of the frame by engagement of the gear 75 with the rack 62, the spring 76 being wound upon the shaft 72 imparts sufficient power to the carriage to keep the cards or envelops at the proper The horizontal portion 5 of the fran'ie is provided with a cut-away portion 77, directly below the feed rollers 36 and The lower fade of said portion, on the outside of the cutaway portion 77, is provided with ears 78, in which is mounted a shaft 79. Carried on said shaft is a roller 80 which extends upwardly through the cut-away portion 77. The-portion 5 of the"frame, below the rollers 46 and 47, is also provided with a'roller 81 which performs the same function as the roller 80. It. has been found that if the feed rigid surface of the frame 5, in rotating in d the proper position. they would be inclined to clench with the frame 5 and stop the operation. Said rollers working in conjunction with the rollers 36 and 37 provide a forward yielding surface and eliminate this tendency.

For the purpose of preventing more than a single envelop or card being fed to the platen of the typewriter. we provide a pivoted pointer stop 83, which is pivoted at 8-1 to the lower face of the frame and having an upwardly extending pointed end 85 extending through an opening 86 in-the frame. This stop, as s'eenin the drawings, is in the rear of the feed rollers 36 and 37. The. stop, below its pivoted point, is provided with a downwardly extending arm 89, carrying a weight 90, whereby it is free to rock upon its pivot. The weight normally holds the point above the frame to prevent.- more than a single envelop or-card passing under the rollers 36 and 37, which is accomplished in the following manner: The pointed end 85 is Weighted to swing with such power as to be sufficient to retard the under envelop from feeding forward with the friction of the envelop immediately in contact with the feed rollers 36 and 37, yet not SlllllClOlli to retard it when it in turn comes in unn'iediate contact with the feed rollers, and in feeding forward it pushes the POlllis forward level with the frame, passes our the. point and bending to pass'nnder the fee t rollers, forms a hollow space whielrperuuts the points 85 to resume their. upright po ition and so retard the next succeeding envelop.

In some instances it is more desirable to operate the shaft 12 by hand. and for this purpose the end of the shaft opposite to that carrying the sprocket wheel is provided with a knob or wheel 91.

The construction and operation of our device will be readily understood from the foregoing description I and accompanying drawings, and it will be appreciated that the parts and combinations thereof may be varied within a wide range without depart ing from the spirit and scope of our invention.
